Cop pulls over speeding doctor. Instead of a ticket, he gives her a stack of masks from his own supply.

A Minnesota police officer gave a hurried doctor who was speeding a handful of masks — rather than a speeding ticket.

What are the details?

A Minnesota police officer pulled over cardiologist Sarosh Ashraf Janjua for speeding on Interstate 35 last week.

Janjua, who lives in Massachusetts but often travels to Minnesota for work, shared the interaction on Facebook, and said that when the unnamed officer pulled her over, she feared the worst: a ticket.

Instead, he handed over five N95 face masks from his own personal stash.

"[The officer] went back to his patrol car to look up my license, and when he returned, quite firmly told me it was very irresponsible of me to be speeding, especially since I would not only take up resources if I got into an accident, but would also not be in a position to help patients," Janjua wrote in the now viral post.

It was at that time he told her that he would let her off with a warning, and handed her the masks.

"As I sputtered to apologize and say thank you, he reached in to hand me what I assumed was my license back," she recalled. "It wasn't until my hand had closed around what he was giving me that its unexpected bulkiness drew my eyes to it."

She continued, "Five N95 masks, from the supply the state had given him for his protection."

What happened next?

Janjua said that she was moved to tears by the officer's kind and selfless gesture.

"I burst into tears," she admitted. "And though it may just have been the cold wind, I think he teared up a little as well, before wishing me well and walking away. Like all health care workers and emergency responders around the world, I have felt afraid of not having adequate protective equipment, and in my darkest moments, have worried about what would happen if I fell sick far from home.

"This complete stranger, who owed me nothing and is more on the front lines than I am, shared his precious masks with me, without my even asking," she concluded. "We are going to be OK."

Janjua appeared on CNN's "Anderson Cooper 360°" this week to share her experience.
